Additional information

I re-installed the windows and webui but keep the old models, extensions in another disc. After re-installing the webui with no problem, I just copy the every single old models and extensions into the new folder. Now I am having an issue with selecting a model. Anyone have an idea to fix it? I recently upgrade my GPU from RTX 3060 to RTX 4060 ti and installed the drivers, cuda, python, git. (I tried to deactivate the extensions and installed new model but it still occurs.)
